A certain amount of anxiety is a vital and healthy defence mechanism in us all. It's function
is to help to prevent us getting into dangerous situations and in the Short-term, low levels help us to perform better at
interviews etc. However anxiety that is severe enough to interfere with our daily activites is not healthy and it's
not usefull. Anxiety conditions are very common and along with depression are the most common psychological conditions
we can suffer and affects many millions of peole in the Uk alone.

For example in The Facts leaflet published by the anxiety charity No-Panic in Telford, Shropshire
it says:

up to five million people in the UK suffer Agoraphobia

up to one million people in the UK suffer Social phobia

up to four million people in the UK suffer Specific phobia

up to two million people in the UK suffer Obsessive Compulsive Disorder

up to two million people in the UK are on tranquilisers long term.

That's the bad news. The good news is that you don't have to put up with anxiety, because
there has been literally a revolution in the recent past in psychopharmacology and also new forms of psychological therapy
like Cognitive Behavioural Therapy have been developed which research has proven can help reduce anxiety suffering.
